The bundle revisions of a bundle. When a bundle is
installed and each time a bundle is updated, a new bundle revision of the
bundle is created. For a bundle that has not been uninstalled, the most
recent bundle revision is defined to be the current bundle revision. A bundle
in the UNINSTALLED state does not have a current revision. An in use bundle
revision is associated with an in useBundleWiring. The current bundle revision, if there is one, and all
in use bundle revisions are returned.
